Hi,
I was using the AT91SAM7X256-EK and am now asked to switch to the development
kit for the AT91SAM7S256 (from the 'X' to the 'S' variant).
I read in the AT91SAM-PROG User Guide that the way SAM-BA boot mode works on the
SAM7Sxxx variant is different to the way it works on the SAM7Xxxx variant of the
uC.
Somehow I can't believe that Atmel would have done this. Can it be that the
doc. is wrong? When I have the kit I'll test it out of course, but it does
mean a pcb change if it's true.
Thanks for any info,
F.
SAM-BA AT91SAMS vs AT91SAM7X

Yes they are different.
The SAM7Xxxx is the never and better variant, so the switch Atmel did was in the "right" direction :)
You you are going to reprogram the SAM7xxx often for experimentation then you should really consider using flash programming through JTAG. For the SAM7Xxxx SAM-BA is OK.
